Features
Titanium ball valve ball is floating, under the media pressure, the ball can produce a certain displacement and squeeze the sealing surface of the outlet end, to ensure that the outlet end of the seal. American standard titanium ball valve is mainly the use of titanium metal materials in strong corrosive environment oxide film has good stability and self-passivation ability, this feature to withstand a variety of harsh conditions of strong corrosion.
1, the flow resistance is small, the ball valve is the smallest of all valves in the fluid resistance, even a reduced diameter ball valve, the fluid resistance is quite small.
2, American standard titanium ball valve sealing performance is good. Ball valve seat (seal) PTFE PTFE and other generally made of flexible materials, easy to ensure that the seal, and ball valve sealing force increases with increasing media pressure.
3, the stem seal is reliable. When the valve is opened and closed, the valve stem only rotates by 90 °, so the packing seal of the valve stem can not be easily damaged, and the sealing force of the valve stem inverted seal increases with the increase of the medium pressure.
